GREM Malware Analysis Techniques & Tools

Question 1

What is the primary goal of static malware analysis?

Accepted Answer

To inspect the code and binaries without execution

Answer

Static malware analysis involves examining the malware's code, structure, and metadata without actually executing it. This method allows analysts to gain initial insights into the malware's potential capabilities, identify strings, imports, and other characteristics, and gather intelligence. It's a crucial first step to understand the threat without risking infection of the analysis environment.

Question 2

Which tool is commonly used for dynamic malware analysis?

Accepted Answer

Process Monitor

Answer

Process Monitor is a powerful utility from Sysinternals that provides real-time monitoring of file system, Registry, and process/thread activity on Windows systems. In dynamic malware analysis, it is invaluable for observing exactly what files, registry keys, and processes a piece of malware interacts with when executed. This detailed visibility helps analysts understand the malware's behavior and impact on a system.

Question 3

What is a sandbox in malware analysis?

Accepted Answer

An isolated environment to safely execute malware

Answer

A sandbox is a critical security mechanism in malware analysis, providing an isolated and secure virtual environment where suspicious files can be safely executed. This allows analysts to observe the malware's behavior, network communications, file modifications, and other actions in a controlled setting without risking infection of the host system or network. The isolation prevents the malware from escaping and causing harm.

Question 4

Which language is often used for scripting malware?

Accepted Answer

Python

Answer

Python is frequently used for scripting malware due to its versatility, extensive libraries, ease of use, and cross-platform compatibility. Its ability to interact with system APIs, perform network operations, and manipulate files makes it an effective language for creating various types of malicious software. The widespread availability of Python interpreters on many systems also facilitates its execution by malware.

Question 5

What does obfuscation mean in the context of malware?

Accepted Answer

Hiding code functionality to evade analysis

Answer

Obfuscation in the context of malware refers to techniques employed by attackers to deliberately make their code difficult to understand, analyze, and detect by security tools and researchers. This involves methods like encryption, packing, and control flow manipulation, all designed to conceal the malware's true functionality and evade signature-based detection. The goal is to prolong the malware's effectiveness and make reverse engineering more challenging.
